Is hemophilia a sex-limited or a sex-influenced trait? If a mother has the hemophilia trait, that means that her son will have hemophilia. Hemophilia, along with color blindness, is a sex-linked recessive trait. Hemophilia is when a person lacks a clotting factor in the blood. This results in the decreased ability to have blood clots. This can be dangerous because a person may internally or externally bleed to death.

Heterophoria With heterotropia, a correcting movement of the eye can be detected already by the simple cover test; with heterophoria, such correcting movement only takes place in the cross-cover test. People with heterophoria are able to create and maintain binocular fusion through vergence, and the cross-cover test purposely breaks this fusion, making the latent misaligment visible.

Congenital Disorders of the Brain Unlike subependymal hamartomas of tuberous sclerosis, which are isointense to myelinated white matter and can also be seen in a subependymal/periventricular location, heterotopias are isointense to gray matter and do not enhance. Subcortical heterotopias differ from periventricular heterotopias in that these nodular masses develop in the white matter as swirling, irregular, curvilinear areas of ectopic gray matter .

A rare form of color vision impairment in which the world is seen only in black, white, and shades of gray. This hereditary disorder of sight is the result of a lack of cone vision; that type of vision which is provided by the cone photoreceptors in the retina. In the normal human eye, it is estimated that there are about six million cone photoreceptors that are located largely in the center of the retina.
